The total amount in the account after interest will be about $4525.63 .
In the fields of finance and economics, interest is the additional sum that is paid by a borrower or deposit-taking financial institution to a lender or depositor at a certain rate (the amount borrowed).
The borrower may be obliged to pay fees to the lender or another entity, but interest is different.Interest also differs from a dividend, which is money given to shareholders (owners) by a company from its profit or reserve but not at a set rate or proportionally;It is a share of the reward or interest received by risk-taking businesspeople when income is generated that exceeds all expenses.Interest when the principal is $4000 , time is 5 years and rate is 2.5%.
We know that from compound interest:
Amount = principal (1 + rate)ⁿ
Therefore
Amount = 4000 (1 +0.025)⁵
Amount = $4525.6328...
Amount ≈ $4525.63
Therefore adding interest the sum would be worth $657.51

example of an event which has a probability of 0. Explain why the probability equals 0.
The example of an event which has a probability of 0 is probability of getting number 7 when you throw a die once. The probability of this event is zero because it will not occur.
The probability is the branch of mathematics that shows the occurrence of the random event. The value of the probability varies from 0 to 1.
The equation of the probability is
Probability = Number of favorable outcomes / Total number of outcomes
The probability of getting number number 7 when you throw a die once is zero. Because when you throw a die the possible outcomes are 1, 2, 3, 4, 5 and 6. We wont get number 7. Therefore the probability is zero
Hence, the example of an event which has a probability of 0 is probability of getting number 7 when you throw a die once. The probability of this event is zero because it will not occur.

Larry can carry a maximum of 60 pounds.
He is already carrying a chair that weighs 20 pounds. He has boxes as well to carry that weigh 5 pounds each.
Which inequality represents all possible values of x, the number of boxes that he can carry?
A. 20x +5 ≤ 60
B. 5x + 20 ≥ 60
C. 20x + 5 ≥ 60
D. 5x + 20 ≤ 60
Answer: Your answer would be D
Step-by-step explanation: The reason why is because in the question it said he is already carrying a 20 pound chair. It then say he can carry some boxes that weigh 5 pounds each. The word each is your keyword. With that you can replace the x variable with some single digit numbers. But you also need to make sure your total is less than or equal to 60 pounds. You would pick the less than or equal to sign since he can only carry 60 pounds or less.

assessed value. The Mariaskis' home has a market value of $97,400.
a. What is the assessed value?
b. What is the yearly real estate tax?
a.) The Assessed value is $43,830
b.) Annual Tax is $2,848.95
Define marked price
'Marked price' is the general price of the thing without any discount. 'discount' is a percentage of the marked price.
Given,
Assessment rate = 45%
Tax rate is $65 per $ 1000 of assessed value
Marked value = $97,400
a.)
To obtain assessed value,
calculate the 45% of $97,400 like that
45/100 = x/97,400
cross multiply the ratios
100x = 45 * 97,400
x = (45 * 97,400) / 100
x = 45 * 974
x = 43,830
Hence,the Assessed value is $43,830
b.)
Find yearly real estate tax,
Assessed value = $43,830
Tax rate is = 65 / 1000 of assessed value
= 0.065 * 43830
= 2,848.95

2.Solve the first equation for y.
3.Solve the second equation for x.
4.Solve the second equation for y.
Using substitution method, the best initial step in solving the equation is solve the first equation for x.
How to solve equation by substitution method?The equation can be solved by substitution method as follows:
2x + 3y = -12
6x + y = 18
Hence, let's make y the subject of the formula in equation(ii)
6x + y = 18
y = -6x + 18
We have to substitute the value of y in equation(i)
2x + 3y = -12
2x + 3(-6x + 18) = -12
2x - 18x + 54 = -12
- 16x + 54 = -12
-16x = - 12 - 54
- 16x = -66
x = 66 / 16
x = 33 / 8
Therefore,
6(33 / 8) + y = 18
99 / 4 + y = 18
y = 18 - 99 / 4
y = - 27 / 4

What is rate of expansion of solid ?For physics, The term "thermal expansion" refers to a material's change in length, width, height, or volume when its temperature is raised or lowered. Solids exhibit particularly noticeable thermal expansion due to their closely packed atoms. There are numerous uses for thermal expansion of solids in daily life.
A solid's atoms vibrate more quickly around their fixed positions when it is heated. As a result, there is little relative growth in the size of solids during heating. In order to prevent buckling when exposed to heat from the sun, metal train tracks feature tiny gaps.
CalculationL = length of a side
A = L2
dA/dt = 2L dL/dt
dL/dt = 8 cm/s
A = 81 cm2 ⇒ L = √A = √81 cm = 9 cm
dA/dt = 2(9cm)(8 cm/s) = 144 cm/s2

Volume of cube = (side)³ = S³ cubic units
Then, as given area in square units of cube = 1/6 of volume of cube in cubic units . That is 6S²= 1/6 S³ => S = 36 units
Area of cube with side 36 units = 6×36²=46656 square units
Volume of cube with side 36 units = 36 ³ cubic units

What is the "Difference of Squares" identity?The difference of the square's identity is shown below:
(a+b)(a-b) = a² -b²
When an expression can be seen as the difference of two perfect squares, i.e. a² -b², we can factor it as (a+b) (a-b).
For example, x²- 49 may be factored as (x+7)(x-7).
This approach is based on the pattern (a+b)(a-b) = a² -b², which may be validated by extending the parenthesis in (a+b)(a-b).

A northbound train and a southbound train meet each other on parallel tracks heading in opposite directions. The northbound train travels 12 miles per hour faster than the southbound train. After 2 hours, they are 240 miles apart. At what speeds are the two trains traveling?
please help me, I'm gonna fail my test tomorrow
Answer:
Speed of northbound train = 66
Speed of southbound train = 54
Step-by-step explanation:
First, let's make the variables simpler:
Speed of southbound train = x
Thus:
Speed of northbound train = y = x + 12
Distance = speed · time
240 = 2 ( x + x + 12 ) = 2 ( 2x + 12 ) = 4x + 24
216 = 4x
x = 54
Now, plug in x to find the speed of the northbound train (y):
y = 54 + 12 = 66
